After unzipping the archive open a console window (cmd.exe) and in there execute
'python3 install.py'. This will install eric in the directory tree of the used
Python interpreter. (On Windows you may need to give the complete path to the
interpreter like c:\Python35\python.exe install.py).

When I install Eric6, i get a .zip file. But after extracting that file, I am at
a loss of what to do. There is no executable file, no IDE, no program, only
directories upon directories. There is a python file called "install" but when i
run it, the command line flashes for a second then disappears. What is happening???
